Benefits of Express Segments
Express segments are a segment routing (SR) abstraction of an underlay path. Express segments facilitate the establishment of end-to-end SR paths using any underlay technology. The underlay technology currently supported are RSVP-TE and SR-TE. Express segment through RSVP-TE underlay is explained below.
In Figure 1, Domain 2 leverages its RSVP-TE underlay LSPs for traffic engineering management and presents those underlay RSVP-TE LSPs as express segments to the adjacent domains (Domain 1 and Domain 3), therefore enabling end-to-end SR-TE path establishment.
Figure 1: Multi-Domain End-to-End SR-TE with RSVP Underlay
Express segments implicitly reduce the size of the SR segment list by compressing them (segment lists) to, at a minimum, one segment ID (SID)/label per domain. This becomes useful when end-to-end traffic engineered constraints would otherwise result in a segment list that exceeds the ingress router's label imposition capabilities. This also becomes beneficial when one or more domains are already implementing SR-TE for traffic engineered path management.
In Figure 2, you can see Domain 2 is using SR-TE and how the use of express segments enables PE1 device to use three labels to traverse the multi-domain network instead of five.
Figure 2: Multi-Domain End-to-End SR-TE with Reduced Label Stack
Express segments allow operators to present an abstraction of the network to adjacent domains and/or higher layer systems.
To establish a traffic engineered path through a series of interconnected domains or multi-domain network, it is necessary to have a certain amount of traffic engineering information about each network domain. Topology abstraction allows the use of policies to connect across domains. Topology abstraction does not necessarily offer all possible connectivity options but presents a view of potential connectivity according to the policies that determine how the domain resources need to be used. The domain could be constructed as a mesh of border node to border node express segments.
Using Figure 2, PE2’s view of an end-to-end traffic engineered system is represented in its local traffic engineering database as shown in Figure 3.
Figure 3: Abstracted Traffic Engineered Domain
Use Cases
This section describes a few use cases for establishing end-to-end SR-TE connectivity. RFC7926 introduces a comprehensive set of terminology and use cases along with an architecture to facilitate traffic engineering link and node information exchange between domains. As Service providers' networks are expanding because of continued growth, multi-domain networks are becoming more prevalent. In these multi-domain networks, it is required to establish an end-to-end traffic engineered path between one or more domains from a source to a destination
Intra and Inter-domain SR-TE Connectivity Using Express Segments
Express segments have the capability to abstract traffic engineering information when the routing information exchange happens between domains. The traffic engineering information used as a criterion for path selection is the data relating to traffic engineered nodes and links. Traffic engineering information may be link metrics such as IGP, traffic engineering, latency, or administrative link attributes such as affinities. Express segments are best described as virtual traffic engineered Links that facilitate the abstraction of underlay LSPs.
Enhanced On-demand Next-hop
Enhanced On-demand Next-hop (EODN) (also known as BGP-triggered SR policies) facilitates the dynamic provisioning of end-to-end SR-TE policies, with constraints, upon the arrival of services routes. In large networks having hundreds of PE devices creating and maintaining traffic engineering policies on any ingress PE for every egress PE is challenging. Considering colors specific services (per VPN or per group of prefixes) makes things even more complicated and harder to maintain and troubleshoot. BGP triggered SR-TE addresses the task by automatically creating dynamic SR tunnels based on pre-configured templates. There is no need to provision ingress PEs with configuration for every egress PE.
How does Express Segment Work?
Express segments can be used to establish end-to-end traffic engineered paths between interconnected traffic engineered networks. Express segments (also known as virtual traffic engineering links) are generated dynamically through policies matching the underlay LSPs. Express segments and the corresponding abstracted topology (required by RFC7926) is generated with policies.
To apply a policy, include the policy policy-name
configuration statement at the [edit protocols express-segment
traffic-engineering] hierarchy level.
Note:
The policy-name is optional. If a policy name
is not defined, then the policy implicitly imports all the express segments into
the local traffic engineering database. An express segment template
automatically creates a one-on-one mapping of express links.
To configure express segment, include the express-segment
configuration statement under the [edit protocols] hierarchy
level.
Let us refer to Figure 1 and use the pair of RSVP-TE LSPs shown between C1 and C4 border nodes and how express segments are generated representing the underlay LSPs. In Figure 4, a policy is created to represent two RSVP-TE (gold and liquid-gold) LSPs as a single express segment.
Figure 4: A Pair of RSVP-TE LSPs Represented as an Express Segment
The following is a sample policy where the policy name is matched through a regular expression and the end-point of the RSVP-TE LSPs:
content_copy zoom_out_map
protocols {
express-segment-set gold-exp-seg {
policy gold;
}
}
policy-options {
policy-statement gold {
from {
route-filter 10/8 {
install-next-hop lsp-regex *gold;
}
}
then accept;
}
}
In the following sample output, you can see the newly created express segment (Gold-Exp-Set-192.168.1.4) along with the traffic engineering attributes are inherited from the underlay RSVP-TE tunnels:
content_copy zoom_out_map
user@C1#show express-segments name gold-exp-seg-192.168.1.4 detail

You can observe the following in the output:
Automatic naming of the express segment (
Gold-Exp-Set-192.168.1.4).Traffic engineering attributes (bandwidth, metrics, admin groups, SRLGs) of the underlay RSVP-LSPs are inherited by the express segment.
The express segment is an unnumbered traffic engineered link and has been added to the traffic engineering database.
Label 19 has been assigned and installed in the
mpls.0forwarding table as the adjacency SID for the SR virtual traffic engineering link.
The following is an example where SR-TE LSP destination is matched:
content_copy zoom_out_map

}
policy-options {

route-filter 3.3.3.3/32 exact;
}
then accept;In the following sample output, you can see the newly created express segment (set1sr-3.3.3.3) from the uncolored SR-TE underlay tunnels:
content_copy zoom_out_map
user@C1show express-segments detail Name: set1sr-3.3.3.3 To: 3.3.3.3, Type: Dynamic (Set: set1sr) Label: 16 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 5d 20:37:08) LinkAttributes: LocalID: 2147483649 TE-Metric: 20, IGP-Metric: 20 BW: 0bps UnderlayPaths: 1 SRTE LSP: lsp1to3_sr TE-Metric: 0, IGP-Metric: 0 BW: 0bps
How are Express Segments Advertised?
Express segments are advertised across domain boundaries or to higher-level controllers and Path Computing Elements (PCEs) using the BGP link state. When exchanging information through the BGP link state, the extensions for the BGP link state are used to advertise express segments as traffic engineered links. The express segment traffic engineered links and other normal traffic engineering links appear in the traffic engineering link-state database of any LSR in the network and are used for computing end-to-end traffic engineered paths. Express segment traffic engineering database entries are imported and exported from the lsdist.0 table for advertisement through the BGP link state with the following traffic-engineering database import and export configuration:
content_copy zoom_out_map
protocols {
mpls {
traffic-engineering {
database {
import {
l3-unicast-topology {
bgp-link-state;
}
policy es_2_bgpls;
}
export {
policy bgpls_2_ted;
}
}
}
}
bgp {
group te-peers {
family traffic-engineering {
unicast;
}
export abstract-topo;
}
}
}
Figure 5 provides a visual representation of how traffic engineering links and nodes are mirrored between the local traffic engineering database and the lsdist.0 RIB that BGP-LS uses for advertisement. As illustrated, there are several policy attachment points.
Figure 5: Advertising Express Segments
How are Express Segments Used by a Path Computing Element?
The BGP link state export policy is an effective place to create an abstract or customized topology that is advertised to a traffic engineered peer. For example, you may want to advertise only the express segment and Domain 3’s TE links and nodes to PE2 such that the traffic engineered topology is abstracted as shown in Figure 6. The abstracted view is then used by PE2 for end-to-end path computation.
Figure 6: Abstracting Traffic Engineered Domain 2 with Express Segment
The following is a sample configuration of a BGP link state export policy on C1:
content_copy zoom_out_map
policy-options {
policy-statement abstract-topo {
from {
traffic-engineering {
protocol express-segment;
ipv4-prefix {
as 3;
}
}
}
then accept;
}
}
The following is a sample SR policy configuration on PE2 router to establish an end-to-end multi-domain path from PE2 to PE3:
content_copy zoom_out_map
protocols {
source-packet-routing {
source-routing-path pe2-to-pe3 {
to 192.168.70.1;
color 10;
primary {
sl1 {
compute {
profile_any-path;
}
}
}
}
}
}
The resulting end-to-end path is represented in Figure 7. You can see the express segment’s adjacency SID (label 19) is used in the SR segment-list resulting in traffic being load-balanced over both the gold and liquid-gold RSVP-TE LSPs within Domain 2.

Requirements
This example uses the following hardware and software components:
MX Series routers as provider edge, border nodes, and intermediate routers.

Overview
The following topology (Figure 8) shows two SR-TE domains (AS100 and AS300) running EBGP-LS inter-connected through an RSVP-TE (AS200) domain:
Topology
Figure 8: Inter-domain SR-TE Connectivity Using Express Segments
In this topology, an end-to-end SR-TE path between PE1 router to PE2 router is established. Egress peer engineering (EPE) segments are defined on PE1 and PE2 routers to steer traffic towards their directly connected border nodes BN1/BN2 and BN3/BN4, respectively. EPE segments defined on the border nodes are advertised internally through the BGP link state. These two SR-TE domains are interconnected through the domain (AS200) that is leveraging RSVP-TE LSPs for internal path establishment.
The border nodes of the AS200 domain facilitate the abstraction of SR-TE information between domains. Express segments are created on border nodes (BN1, BN2, BN3, and BN4). Express segments are created in a one-on-one relationship with the underlying RSVP-TE LSPs and all express segments are inserted into the border node's local TE database for subsequent BGP link-state advertisement. The AS200 domain leverages RSVP-TE LSP underlays for TE management and presents those underlay RSVP-TE LSPs as express segments to the AS100 and the AS300 domains, enabling the domains to have end-to-end SR-TE LSP connectivity.

Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R0:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.

After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.

Configure R4 (BN2 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R4:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R4#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure R2 (Intermediate router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R2:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R2#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure R6 (BN4 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R6:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R6#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure R7 (PE2 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R7:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R7#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Verification
To confirm that the configuration is working properly, perform the following tasks:
- Verify the Express Segment
- Verify the Express Segment Advertisements
- Verify the TE Topology Information
Verify the Express Segment
Purpose
Verify that the express segments are created correctly.
Action
From operational mode, run the following commands:
show express-segments detail—Verify whether the express segments are created.show ted database topology-type express-segments detail—Verify that the newly created express segments are inserted into the TE database.show route table mpls.0 protocol express-segments—Verify whether the forwarding entries have been created.

Meaning
In the
show express-segments detailoutput, you can see the name of the express segments (r1-exp-set1-10.6.6.6, r1-exp-set2-10.3.3.3), express segment labels (25, 24), and the underlay LSPs (lsp1to6_a, lsp1to3_a).In the
show ted database topology-type express-segments detailoutput, you can see the express segment entries are inserted into the TE database. The express segments (virtual TE links) are dynamically created. The protocol used is EXPRESS-SEG(0).In the
show route table mpls.0 protocol express-segmentsoutput, you can see the express segment labels (24,25). Because the express segment is a construct that relies on the underlay LSPs, the express segment label gets swapped to the underlay LSP labels (33,34), which is RSVP-LSP.
Verify the Express Segment Advertisements
Purpose
Verify that the originating node advertises express segments to its eBGP/iBGP LS neighbors.
Action
From operational mode, run the following commands:
show route table lsdist.0—Verify that the express segments in the RIB BGP-LS are being advertised.show route advertising-protocol bgp neighbor—Verify that the express segments are sent to the eBGP/iBGP LS neighbors.

Meaning
In the
show route table lsdist.0output, BGP advertises the routes in the routing table. The routing table is created from the TE database. You can see the express segments (EXPRESS-SEG/6) links and the EPE links (BGP-LS-EPE:0 }/1216).In the
show route advertising-protocol bgp 10.2.2.2output, you can see what R1 is advertising to. The express segments are inserted into the TE database, which is copied to RIB. BGP-LS advertises the RIB to the peer router. On the peer, the received RIB information is copied into the local database. The policy in this example only advertises express segments and EPE segments.
Verify the TE Topology Information
Purpose
Verify that the ingress nodes receive TE topology information through eBGP/iBGP LS.
Action
From operational mode, run the following commands:
show route receive-protocol bgp neighbor—Verify that the express segments are received from eBGP/iBGP LS neighbors.show route table lsdist.0—Verify that the express segments are in the BGP-LS RIB.show ted database topology-type l3-unicast detail—Verify that the express segments are imported into the ingress router’s TE database.show spring-traffic-engineering lsp—Verify that the end-to-end SR policy has been successfully computed and installed.

Example: Inter-domain SR-TE Connectivity Using Express Segments Through SR-TE Underlay
Use this example to learn how to establish an end-to-end inter-domain SR-TE connectivity using express segments through SR-TE underlay.
Requirements
This example uses the following hardware and software components:
MX Series routers as provider edge, border nodes, and intermediate routers.
Junos OS Release 21.2R1 or later releases.
Overview
The following topology (Figure 9) shows two SR-TE domains (AS100 and AS300) running EBGP-LS inter-connected through another SR-TE (AS200) domain:
Topology
Figure 9: Inter-domain SR-TE Connectivity Using Express Segments
Through
SR-TE Underlay
In this topology, an end-to-end SR-TE path between PE1 router to PE2 router is established. Egress peer engineering (EPE) segments are defined on PE1 and PE2 routers to steer traffic towards their directly connected border nodes BN1/BN2 and BN3/BN4, respectively. EPE segments defined on the border nodes are advertised internally through the BGP link state. These two SR-TE domains are interconnected through the domain (AS200) that is leveraging SR-TE LSPs for internal path establishment.
The border nodes of the AS200 domain facilitate the abstraction of SR-TE information between domains. Express segments are created on border nodes (BN1, BN2, BN3, and BN4). Express segments are created in a one-on-one relationship with the underlying SR-TE LSPs and all express segments are inserted into the border node's local TE database for subsequent BGP link-state advertisement. The AS200 domain leverages SR-TE LSP underlays for TE management and presents those underlay SR-TE LSPs as express segments to the AS100 and the AS300 domains, enabling the domains to have end-to-end SR-TE LSP connectivity.
The following table describes the domains, routers, and connections in the topology:

Configure R0 (PE1 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R0:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R0#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Define import and export policies. For example, configure policies that export EPE TE links from the local TE database to lsdist.0 and policies to import from lsdist.0 into the local TE database. You can configure policies to advertise the BGP routes to a peer.
Route filter routs are advertised from external AS.

Configure R1 (BN1 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R1:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R1#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure R4 (BN2 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R4:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R4#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R2#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Configure R5 (Intermediate router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R5:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R5#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete

Configure R3 (BN3 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R3:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R3#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Define a mechanism to automatically (dynamic) create express segments and insert them in to the TE database so that they can be advertised through BGP-LS. In this example, express segments are created for all the underlay SR tunnels automatically. This is done by configuring a template with a policy and then express segments are automatically created based on the policies.

Configure R6 (BN4 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R6:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R6#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Define a mechanism to automatically (dynamic) create express segments and insert them in to the TE database so that they can be advertised through BGP-LS. In this example, express segments are created for all the underlay SR tunnels automatically. This is done by configuring a template with a policy and then express segments are automatically created based on the policies.

Configure R7 (PE2 router)
Step-by-Step Procedure
The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.
To configure device R7:
Configure the network services mode as Enhanced IP. Enhanced IP sets the router's network services to enhanced Internet Protocol and uses enhanced mode capabilities.
content_copy zoom_out_map[edit] user@R7#set chassis network-services enhanced-ip
After you configure the
enhanced-ipstatement and commit the configuration, the following warning message appears prompting you to reboot the router:content_copy zoom_out_map'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
The reboot brings up the FPCs on the router.
Configure the interfaces to enable IP, MPLS, and ISO transport.

Define import and export policies. For example, configure policies that export EPE TE links from the local TE database to lsdist.0 and policies to import from lsdist.0 into the local TE database. You can configure policies to advertise the BGP routes to a peer.
Route filter routs are advertised from external AS.

Verification
To confirm that the configuration is working properly, perform the following tasks:
- Verify the Express Segment
- Verify the Express Segment Advertisements
- Verify the TE Topology Information
Verify the Express Segment
Purpose
Verify that the express segments are created correctly.
Action
From operational mode, run the following commands:
show express-segments detail—Verify whether the express segments are created.show ted database topology-type express-segments detail—Verify that the newly created express segments are inserted into the TE database.show route table mpls.0 protocol express-segments—Verify whether the forwarding entries have been created.

In the
show express-segments detailoutput, you can see the name of the express segment (set1sr-10.3.3.3), express segment label (16), and the underlay LSP (lsp1to3_sr).In the
show ted database topology-type express-segments detailoutput, you can see the express segment entries are inserted into the TE database. The express segments (virtual TE links) are dynamically created. The protocol used is EXPRESS-SEG(0).In the
show route table mpls.0 protocol express-segmentsoutput, you can see the express segment label (16). Because the express segment is a construct that relies on the underlay LSPs, the express segment label gets swapped to the underlay SR-TE labels (801003).
Verify the Express Segment Advertisements
Purpose
Verify that the originating node advertises express segments to its eBGP/iBGP LS neighbors.
Action
From operational mode, run the following commands:
show route table lsdist.0—Verify that the express segments in the RIB BGP-LS are being advertised.show route advertising-protocol bgp neighbor—Verify that the express segments are sent to the eBGP/iBGP LS neighbors.

Meaning
In the
show route table lsdist.0output, BGP advertises the routes in the routing table. The routing table is created from the TE database. You can see the express segments (EXPRESS-SEG/6) links and the EPE links (BGP-LS-EPE:0 }/1216).In the
show route advertising-protocol bgp 10.2.2.2output, you can see what R1 is advertising to. The express segments are inserted into the TE database, which is copied to RIB. BGP-LS advertises the RIB to the peer router. On the peer, the received RIB information is copied into the local database. The policy in this example only advertises express segments and EPE segments.
Verify the TE Topology Information
Purpose
Verify that the ingress nodes receive TE topology information through eBGP/iBGP LS.
Action
From operational mode, run the following commands:
show route receive-protocol bgp neighbor—Verify that the express segments are received from eBGP/iBGP LS neighbors.show route table lsdist.0—Verify that the express segments are in the BGP-LS RIB.show ted database topology-type l3-unicast detail—Verify that the express segments are imported into the ingress router’s TE database.show spring-traffic-engineering lsp—Verify that the end-to-end SR policy has been successfully computed and installed.

Meaning
In the
show route receive-protocol bgp 192.168.1.2output, it shows the routes that have been received by the ingress router (R0) from the BGP neighbor, which describes the express segment (virtual TE links).In the
show route table lsdist.0output, it shows the routes that have been received by the ingress router (R0) and whether they are inserted into the lsdist.0 RIB. It also shows whether the lsdist.0 RIB is copied into the local TE database.In the
show ted database topology-type l3-unicast detailoutput, the routes are copied into the local TE database. The set1sr-10.3.3.3 is an express segment with end point as 3.3.3.3 and is successfully created on R1. R1 has advertised the express segment and R0 has inserted it into the local TE database. You can also see the EPE segments (epe_adj1_toR7).In the
show spring-traffic-engineering lspoutput, you can see that the SR policies are up. It shows that you are now able to compute a multi-domain end-to-end (R0 to R7) SR policy.In the
show spring-traffic-engineering lsp detailoutput, you can see the labels that are selected. In the computelsp1 LSP, the label 7101 is an EPE segment, 16 is the express segment, and 7137 is also an EPE segment. It shows that you are now able to compute a multi-domain end-to-end (R0 to R7) SR policy.
